Description

  The present invention relates to a door locking device that opens and closes a doorway provided on a side wall of a vehicle.

One of the door opening and closing methods that opens and closes the door opening of the vehicle is a sliding mechanism that supports the sliding door slidably in the longitudinal direction of the vehicle using only the sliding mechanism provided at the center of the upper and lower sides of the sliding door. A vehicle equipped with a swing slide door that eliminates the above is known, and an example thereof is described in Patent Document 1.
By the way, when the door opening of the vehicle is held in the closed state by the swing slide door, for example, as shown in FIG. 15, the swing slide door 200 swings and is displaced by the parallel link 201 or the like to reach the closed position D1. At that time, the front and upper two lock portions J1 and J2 (only the upper portion is shown in FIG. 15) and the latches 202 in the rear rear lock portion J3 are engaged with the strikers 203, thereby swinging the slide. The door is locked to the door opening.

When an electric power latch is used here, as shown in FIG. 16, when the forks 204 in the latches 202 of the lock portions J1, J2, and J3 are engaged with the striker 203, first, The position latch SWA detects the half-latch state (see the broken line) where the fork 204 faces the striker 203, and after the half-latch state is confirmed, the switching lever 207 which is a swing operation member interlocked with the drive gear 206. Is driven to engage the fork 204 with the striker 203 to switch to the full latch state (see the two-dot chain line).
In this case, for example, the two latches 202 (see FIG. 15) of the two upper and lower lock portions J1 and J2 on the front side of the swing slide door 200 are driven by one front motor (not shown), and the rear rear side. A system is employed in which the latch 202 of the lock portion J3 is driven by another rear motor (not shown).

  As described above, the two latches 202 in the lock portions J1 and J2 provided at the two upper and lower positions of the swing slide door 200 are driven by one front motor, and the latch 202 of the rear rear lock portion J3 is moved. When driven by another rear motor, two motors are required, which is disadvantageous in terms of cost, vehicle weight, and effective use of space, and when two motors operate simultaneously, the operation noise becomes relatively loud. There is a problem.

  Therefore, as shown in FIG. 17, the drive gear 301 interlocked with the motor swings the swing operation member 300 from the reference position A to one position B q1, so that the lock portions J1 and J2 at the two upper and lower lock portions J1 and J2 are moved. The latch 202 is switched from the half latch state to the full latch state, and then the swing operation member 300 is returned to the reference position A. Next, the swing operation member 300 is swung q2 from the reference position A to the reverse position C, thereby switching the latch of the rear rear lock portion J3 from the half latch state to the full latch state, and then performing the swing operation. It is conceivable that the two front-side and one rear-side lock portions are switched to a full latch with one motor by a double-sided reciprocating swinging operation (reference position return control) of returning the member 300 to the reference position A. In such a configuration, the swing operation member 300 is returned to the reference position A so that the swing operation member does not hinder the movement of the fork 204 (see the solid line in FIG. 17) when the door is opened after the full latch. it can. However, as shown in FIG. 14, in mode 2 (M2) in which the reference position return control is performed after the closing operation of each latch, the front and rear latches are operated in order and the door is closed to complete the closing (in the drawing). The time until the operation is completed) is twice as long as that in the mode 1 (M1) in which the two front and rear motors are driven at the same time, which causes a problem that the passenger feels uncomfortable.

  The present invention has been made on the basis of the above problems. The object of the present invention is to reduce the operation time of at least two front and rear latches relatively quickly by using forward / reverse rotation of one motor. It is an object of the present invention to provide a door locking device that is operated by a deadline and does not give an uncomfortable feeling to a passenger.

And the latch of the one side lock portion is switched from the half latch position to the full latch position, the swing operation member is reversed in the other direction by a second predetermined width, and the other side is Switches the latch of the lock portion fully latched position from the half-latched position, wherein the first predetermined width second predetermined width is configured so as to overlap, characterized in that.

  According to a second aspect of the present invention, in the door locking device according to the first aspect of the present invention, the control device further includes a control unit that drives and controls the latch driving unit. When the swing operation member is swung in one direction, the latch of the one side lock portion is switched from the half latch position to the full latch position, and when the same side lock portion is switched to the full latch position, the swing operation member is moved in the other direction. When the other side lock portion is switched from the half latch position to the full latch position and the other side lock portion is switched to the full latch position, the swing operation member is further reversed to swing back by a predetermined width. It is characterized by that.

  According to a third aspect of the present invention, in the door locking device according to the first or second aspect, the latch driving means is interlocked with the latch of the other side lock portion when the swing operation member is reversed. A switching lever that switches to a linkage position that switches the latch of the other side lock portion from a half latch position to a full latch position and an idle operation position that releases the linkage with the latch of the other side lock portion is provided. .

  According to the first aspect of the present invention, after the swing operation member is swung in one direction by a first predetermined width and the latch of the one side lock portion is switched to the full latch position, the swing operation member is moved in the second direction in the second direction. Since the latch of the other side lock part is switched to the full latch position by reversing the predetermined width, there is no need to add a motor, the cost can be reduced, the weight of the device can be reduced, the degree of freedom of layout in the door is further improved, In addition, since the first predetermined width and the second predetermined width overlap, the one side lock portion and the other side lock portion are relatively quickly moved from the half latch position to the full latch position, and the operating time is shortened and the closing operation is performed. And it does not give the passenger a sense of incongruity.

  According to the second aspect of the present invention, the latch of the one side lock portion is switched to the full latch position by swinging the swing operation member in one direction, and the latch of the other side lock portion is moved to the full latch position by swinging in the other direction. Since the switching operation and the swinging operation member are reversed and swung back by a predetermined width, the unlocking operation force of the latch is increased as in the case where the pulling is stopped at the door closing position, and the durability of the electric open drive device is increased. And manual operability can be prevented from deteriorating.

  According to a third aspect of the present invention, the latch driving means includes an interlock position for switching the latch of the other side lock portion to the full latch position in conjunction with the swing operation member when the swing operation member is reversed, and an empty for releasing the interlock. Since the switching lever for switching to the operating position is provided, the latch of the other side lock portion can be driven and released reliably.

As a result, when the latch release driving means 80 is driven and the poles 881 and 882 of the front upper and lower lock portions J1 and J2 and the rear lock portion J3 are released, the respective pivots rotate around the pivot pins 873 and 883. As a result, the forks q and q1 can return to the unlatched position shown in FIG. 6A from the locked position shown in FIG. 7B.
Next, the operation of the rear door 4 will be described together with the door lock control routine of FIG. This door lock control routine is executed at a predetermined control time in a main routine (not shown) performed by the controller 30, that is, whenever the rear door 4 approaches the closed position D1.
Here, in step S1, the controller 30 determines whether the rear door 4 is in the closed position (see FIG. 1) D1. If so, the process proceeds to step S2, and if the rear door 4 is open, the process proceeds to step S4.

In step S2, it is determined whether or not a door opening command has been received. If not received, the rear door 4 maintains the closed position D1 and returns directly to the main routine (not shown). Otherwise, the process proceeds to step S3.
If No in step S2, when the rear door 4 holds the closed position D1, the latches 661 and 671 of the front upper lock portion J1, the front lower lock portion J2, and the rear end lock portion J3 on the rear door 4 side are locked. The state is kept in a non-energized state. That is, the rear door 4 is locked to the center pillar 5 using the latch 661 and the striker 662 of the front upper lock portion J1 (the same applies to the front lower lock portion J2). Further, the latch 671 of the rear lock portion J3 meshes with the striker 672. In this case, as shown in FIG. 3A, the swinging ends of the rear arm 32 and the front arm 31 are drawn into the vehicle interior, and the door support rail 22 closes the rear door 4 together with the slider 24 of the swinging ends of both arms. The position (see FIG. 1) D1 is held.

When the door opening command is received and the process proceeds to step S3, a lock release command is issued from the controller 30, and the branch operation member 802 of the latch release drive means 80 is swung from the steady position to the release position. In conjunction with this, the pole 881 of the front upper and lower lock parts J1, J2 and the release lever 85 of the rear lock part J3 are simultaneously released from the state of FIG. 661 disengages the latch 671 from the striker 672 and switches the front upper, lower lock portions J1, J2 and rear lock portion J3 to the unlatched position, as shown in FIGS. 6 (a) and 8 (a).
As a result, the rear door 4 is opened from the closed position D1, and swinging toward the protruding position D2 is allowed.

At this time, on the open / close control processing routine side of the main routine (not shown), the motor 101 of the drive source M is driven, and the anchor portion of the opening operation cable 49 is connected as shown by a two-dot chain line in FIG. A cable stretched between the cable end poe and the fixed pulley po <b> 1 on the door support rail 22 is wound by an unillustrated open winding portion of the winding drum 46. As a result, the front arm 31 and the rear arm 32 interlocked therewith are oscillated and displaced from the closed position D1 to the oscillating position D2 shown in FIG.
Next, the door support rail 22 side is illustrated relative to the slider 24 at the oscillating end of the parallel link 16 where the rear door 4 passes the oscillating position D2 and stops oscillating by the action of the opening / closing drive mechanism 19. The sliding operation is performed up to the fully open position D3 shown in 3 (c).

Next, assume that step S4 is reached.
Here, the passenger gets on and off using the rear entrance 3 and waits for the controller 30 to receive a door closing command. At this time, the motor 101 is driven to return to the swing position of FIG. 3B from the state of FIG. 3C, and the rear door 4 moves toward the closed position D1 of FIG.
In step S5, it is determined whether the rear door 4 is directed to the closed position D1, and the front upper and lower lock portions J1, J2 have reached the half latch position. As shown in FIG. 6B, when the front upper lock portion J1 and the front lower lock portion J2 reach the half latch state, the changeover switch sw1 issues a half latch on signal, and the controller 30 (control means) accordingly. Drives the latch driving means 81 so that the swing operation member 82 swings in one direction r1, and the front upper and lower lock portions J1 and J2 are fully latched from the half latch state (see FIGS. 7A and 8B). (Step S6). When the changeover switch sw2 issues a full latch-on signal, the process proceeds to step S7. That is, the front upper and lower lock portions J1 and J2 of the rear door 4 are simultaneously switched from the half latch position (see FIG. 6B) to the full latch state (see FIG. 7A), and the engagement of the striker 662 by the fork portion q advances. , A forward pulling movement occurs. Thereby, the rear end side of the rear door 4 can swing around the pivot line connecting the meshing points of the front upper and lower lock portions J1 and J2.

  In step S7, as shown in FIGS. 6B and 7A, when the rear lock portion J3 detects the half latch state, the process proceeds to step S8. In response to this, the controller 30 (control means) drives the latch driving means 81 so as to swing the swing operation member 82 in the other direction r2, and the latch 671 of the rear lock portion J3 is changed from the half latch state to the full latch state (FIG. 7). (B), switch to FIG. 8 (c). That is, the rear lock portion J3 of the rear door 4 is switched from the half latch position to the fully latched state, the meshing of the striker 672 by the fork portion q1 proceeds, and the forward pulling movement occurs. As a result, as shown in FIG. 3A, the rear end of the rear door 4 around the pivot line connecting the meshing points of the front upper and lower lock portions J1 and J2 is the full latch equivalent position FRR from the half latch equivalent position HRR (the entire rear door 4). Is turned to the closed position D1, and the changeover switch sw4 is turned on, and the process returns to the main routine.

FIG. 14 is a conceptual explanation chart for shortening the latch cutoff time.
Here, mode 1 (M1) indicates a case where the front upper and lower lock portions J1 and J2 are independently driven and controlled by a single latch driving means and the rear lock portion J3 is independently driven and controlled, respectively. As shown in FIG. 17, mode 2 (M2) is a conventional mode in which both-way reciprocating swing control is performed in which the reference position A is reciprocated from the reference position A to the one position B, then returned to the reference position A and then reciprocated to the other position C. This case is shown. Mode 3 (M3) indicates a case where the deadline stop control shown in FIGS. 1 to 7 is performed.
6 and 7 can be driven in mode 3 (M3), and in this case, a relatively large shortening time T1 can be ensured compared with the latch cutoff time in mode 2, and the latch cutoff can be secured. There is an advantage that time is significantly reduced.

  Further, in the door locking device shown in FIGS. 6 and 7, the front upper and lower lock portions J1 and J2 provided on the front opening edge of the door opening 3 and the rear lock provided on the rear opening edge. Since the part J3 is provided so as to be interlocked with each other, the controller 30 controls the forward rotation and reverse rotation of one motor M1, so that one of the two front upper lock parts J1 (front lower lock part J2) in order is interlocked. And the other rear lock portion J3 can be sequentially locked. For this reason, it is not necessary to add a motor, the cost can be reduced by the single motor M1, the weight of the apparatus can be reduced, and the degree of freedom of layout in the door is further improved.

  Further, in the door locking device shown in FIGS. 6 and 7, the swing operation member 82 is swung in one direction r1 to switch the latch 661 of the front lock portions J1 and J2 to the full latch position, and then the swing operation member 82. When starting the swing r2 in the other direction, the switching lever 83 switched to the interlocking position g2 switches the latch q1 of the rear lock portion J3 from the half latch position to the full latch position (see FIG. 7B). Can do. In other words, the swing operation member 82 moves forward (1) (in the drawing) by a predetermined swing width (first predetermined width) in one direction r1 from the base position A (see FIGS. 6A and 9). Is indicated by a circle 1 and then reversed and moved backward (2) (indicated by a circle 2 in the figure) by a predetermined swinging width (second predetermined width) in the other direction r2. Actuate back to A.

  In particular, as shown in FIG. 9, after the front upper and lower lock portions J1 and J2 reach the full latch, the swing operation member 82 is reversed from one direction r1 to the other direction r2, and the closing operation of the rear lock portion J3 is the base point. A predetermined swing width (1) in one direction r1 (circle 1 in the figure) (first predetermined width) and a predetermined swing width in the other direction r2 so as to be able to be performed before returning to the position A (1). 2) (circle 2 in the figure) (second predetermined width) overlaps. Accordingly, the front lock portions J1, J2 and the rear lock portion J3 can be operated by closing each other relatively quickly from the half latch position to the full latch position without causing a sense of incongruity to the passenger. In addition, since the swing range of the swing operation member 82 can be made relatively small (see swing widths (1) and (2) in FIG. 9 (shown as circles 1 and 2 in the figure)), the rear door 4 The degree of freedom in the layout is improved.

  In the door locking device mounted on the rear door 4 described above, as shown in FIGS. 6 and 7, the swing operation member 82 is moved in one direction r1 from the base position A (see FIGS. 6A and 9). 7b until the next door opening command is input by moving back to the one end position B and then returning in the other direction r2 and returning to the base position A as shown in FIG. The latches q of the front lock portions J1 and J2 and the latch q1 of the rear lock portion J3 are held so as to stop closing while being switched to the full latch position.

Instead of this, as shown in FIGS. 11, 12, and 13, a door locking device that switches to holding for a moment after stopping the deadline may be configured.
This door locking device is different from the above-described door locking device for stopping the closing, except that the engagement position of the swing operation member 82 and the drive gear 811 meshing with this and the switching control are different. This is the same as the opening / closing device for the rear door 4 described with reference to FIGS. 1 to 3 and will not be further described below.
Here, a door locking device that switches to instantaneous return holding will be described with reference to FIGS. 11 (a), 11 (b), 12 and 13. FIG.

  As shown in FIG. 11 and FIG. 12, the swing operation member 82 and the drive gear 811 meshing therewith move forward in one direction r1 from the base point position A, reach one end position B, and then reverse. When returning in the direction r2 and returning to the base position A, it further swings in the same direction r2 and reaches the other end position C, reverses again and returns in the one direction r1 and returns to the base position A. . Here, a predetermined swing width (1) in one direction r1 (circle 1 in the figure) (first predetermined width) and a predetermined swing width (2) in the other direction r2 (circle in the figure). 2) (second predetermined width) overlaps, and in addition to this, it swings with a predetermined swing width (3) (shown as a circle 3 in the figure) in the other direction r2 further from the base point position A. It reverses after the movement and moves backward by a predetermined swinging width (4) (denoted by a circle 4 in the figure) to return to the base position A.

Next, the operation of the rear door 4 will be described together with the door lock control routine of FIG. This door lock control routine is executed at a predetermined control time in a main routine (not shown) performed by the controller 30 in FIG. 2, that is, whenever the rear door 4 approaches the closing position D1.
Here, the same processes as those in steps S1 to S8 which are processes in the door lock control routine of FIG.
The process waits for the rear door 4 to hold the closed position (see FIG. 1) D1, and if held, the process proceeds to step S2, and if the rear door 4 is open, the process proceeds to step S4. In step S2, the process waits for the door opening command to be received. Here, the controller 30 issues a lock release command, and the branch operation member 802 (see FIG. 5) swings to the release position. In conjunction with this, the front upper and lower lock portions J1 and J2, the pole 881 and the rear lock portion J3. The release lever 85 and the interlocking pole 882 are simultaneously released. In response to this, the latch 661 is released from the striker 662 and the latch 671 is released from the striker 672. As shown in FIG. 11A, the front upper, lower lock parts J1, J2 and rear lock part J3 are switched to the unlatched position. The rear door 4 is opened, and swinging toward the protruding position D2 is allowed.
At this time, the rear door 4 is swung from the closed position D1 to the swing position D2 by the opening / closing control process of the main routine (not shown), and further, the rear door 4 passes the swing position D2, and FIG. Is slid to the fully open position D3.

Next, in step S4, the controller 30 waits for the door closing command to be received. When the door closing command is received, the motor 101 is driven, and the rear door 4 moves to the closing position D1 in FIG.
When step S5 is reached, the rear door 4 approaches the closed position D1, and when the front upper and lower lock portions J1, J2 reach the half latch position, the changeover switch sw1 issues a half latch on signal to step S6. move on. Here, the latch driving means 81 swings the swing operation member 82 in one direction r1 from the reference position A (refer to (1) in FIG. 12 (circled 1 in the figure)). When the half-latch state is switched to the full-latch state (see FIG. 7A) and the swing operation member 82 reaches one side position B, the change-over switch sw2 issues a full latch-on signal, and the process proceeds to step S7.

In step S7, if it is confirmed that the rear lock portion J3 of the rear door 4 is in the half latch position (see FIG. 7A), that is, if it is determined that the swing operation member 82 is in the one side position B, step Proceed to S8.
In step S8, the swing operation member 82 is swung in the other direction r2 from the one side position B (see (2) in FIG. 12 (circled 2 in the figure)), and the latch 671 of the rear lock portion J3 is half latched. The state is switched to the full latch state (see FIG. 7B). That is, the engagement of the striker 672 by the fork part q1 proceeds.

When step S8 is reached from step S8, the swing operation member 82 reaches the other side position C (see (3) in FIG. 12 (circled 3 in the figure)), and the step is performed when the changeover switch sw4 is turned on. Proceed to S10. Here, the swing operation member 82 is swung back by a predetermined time t1 toward the reference position A that is one direction r1 (see (4) in FIG. 12 (circled 4 in the figure)). Return to the main routine.
At this time, as shown in FIG. 12, the controller 30 swings the swing operation member 82 in the other direction r2 ((2) (circle mark 2 in the figure)), reaches the reference position A, and the changeover switch sw4. Then, the swing operation member 82 is swung (3) in the other direction r2 beyond the reference position A (circle 3 in the figure). Next, it is oscillated for t1 in a reverse direction r1 for a certain time (4) (circled 4 in the figure) and reciprocated.

Since the swing operation member 82 is returned for a moment by the momentary return operation after the change-over switch sw4 is turned on, the latch change lever 84 is separated from the fork q1, and a gap ta is secured between them (FIG. 11 (b)). )reference). At the same time, as shown in FIG. 3A, the rear end of the rear door 4 is rotationally displaced from the half latch equivalent position HRR to the full latch equivalent position FRR (the state in which the rear door 4 as a whole reaches the closed position D1). Sw4 is kept on, and the process returns to the main routine.
Note that mode 4 (M4) of instantaneous reciprocation as shown in FIGS. 11 (a), 11 (b), 12 and 13 is shown in the conceptual explanation chart for shortening the latch closing time in FIG.

  In this mode 4 (M4), a relatively large shortening time T1 can be secured as compared with the latch cut-off time (when operation is completed) in mode 2 (M2), and a clearance ta is secured between the latch switching lever 84 and the fork q1. Therefore, when the latch release driving means 80 is driven, the fork q1 can quickly return to the unlatched position when the release lever 85 releases the pawl 882 of the rear lock portion J3. That is, when there is no gap ta, receiving the load by the latch switching lever 84 increases the unlocking operation force of the latch q1, and the durability and manual operability of the latch release drive means 80 (electric open drive device) deteriorates. There is an advantage that the latch release driving can be easily and surely performed.
